CALL-BECCBDING APPARATUS FOR TELEPHONES.

Specification of Letters Iatent.

Patented Jan. 21, 1919.

Application fled November 22. 1916. Serial No. 132.742.

To all whom it may concern:

Be it known that I, CHARLES E. BEDAUX, a citizen of the Republic of France, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Call-Recording Apparatus for Telephones, of which the followlng is a specification.

The present invention relates to callrecording apparatus for telephones, and its object is, generally, to provide improved apparatus whereby the person calling by telephone may record at the telephone called the number of the calling telephone in case his call meets no response; and more particularly, to provide such arr apparatus which, with its movable markable element for receiving such numbers, shall not be in operative movement except when the telephone is called.

This and any other objects appearing hereinafter are attained by, and the invention finds preferable embodiment in, the illustrative structure hereinafter described and illustrated by the accompanying drawings, in which Figure l is a front view of a telephone and my call-recording apparatus with the electric calling and call-recording circuit therefor, including a suitable source of electric energy, diagrammatically shown;

Fig. 2 is a view of the call-recording apparatus, the front of its casing being removed and certain parts sectioned on a vertical plane to show the far half only of the electromagnet, for the sake of clearness;

Fig. 3 is a sectional view of the same taken on a horizontal plane corresponding to line AB of Fig. 2;

Fig. 4: is a view of the same looking from the right-hand side of Fig. 2;

Fig. 5 is a detail View of mechanism for stopping and releasing the clockwork which moves the markable element; and,

Figs. 6, 7 and 8 are views of the same in diiferent positions.

In the embodiment of the invention chosen for detailed description in the body of this specification and for illustration by the drawings, a markable element adapted to be marked by a marker, as hereinafter explained, is movable relatively to such marker. As illustrated by the drawings the markable element, a paper strip 1, is moved at uniform speed by means of suitable clockwork (designated generally 2) by a. feed roll 3 on one of the clockworks shafts 4, and passes between said roll and a suitable presser roll 5. The strip is thus drawn from a reel 6 and over the idler roll 7 whereon it is marked in passing by a marker, as the pencil 8. This marker is vibrated sidewise to make the marks on the strip shown in Fig. 3 by being operatively connected to a member movable by the callin apparatus, such member being the pivota ly mounted armature 9 of the electro-magnet 10 in a branch 11 of the electric circuit 12 which includes the calling apparatus, indicated by the call bells 13, of the called telephone 14.

When the person calling presses the call button, indicated at 15, of his calling telephone, the bells ring and the pencil vibrates. Thus, a system of markings by dots and dashes being predetermined, the person call lng by closing the circuit as by pressing the call button of his own telephone, may record on the markable element of the call-recordmg device of the called telephone 14 the proper combination of dots and dashes, represented by the zigzag marks 16, which indicates the member of the callin telephone.

When the call button is presse the vibration of the movable member (the armature 9) strikes a pin 17 of the movable releasing member 18 carried by a rotatable element 19 of the clockwork, and moves it out of the holding engagement of the detent pin 20 (see Fig. 5), whereupon the spring 21 presses the releasing member upwardly, it sliding in its slots 22, 23, an angularly disposed extension 24 of one of which slots has previously held the releasable memberagainst said spring by engaging the detent pin 20. The upper end of the releasing member now strikes and raises the pin 25 of the movable and pivotally mounted stop 26 out of the notch or contact portion 27 of the rotatable element (see Fig. 6) and against the pressure of the spring 28, so that the clockwork is no longer stopped, but is permitted to run and move the record strip. During a rotation of the rotatable element 19, the pin 25 rides on its periphery (see Fig. 7) and the person calling may during this time record his call on the moving strip, the time required for such rotation being of course so regulated as to afford sufficient time for such recording. If the person calling presses the call button of his own telephone for a long time (for inwork is released and a long dash is made on the markable element. If he receives no response, he immediately and while the clockwork continues to run, presses his call button a number of short and long times to correspond with the combination of dots and dashes which identifies his own telephone by its number. As the rotatable element continues its turning movement, the pin '29 of the releasing member strikes the extremity of the swinging arm 30, pivotally mounted on the frame as shown, and is moved on the pins 20, 31 thereby and against the pressure of its spring 21, and into its initial position shown in Fig. 5, the spring 21 drawing the releasable member sidewise sufiiciently to cause the extension 24 of the slot 23 to holdingly engage the detent pin 20. lVhen the rotatable member has completed its revolution, the pin 25 of the stop 26 falls into the notch-27 and stops the clockwork. The stop 26 may be provided with an extending portion 32 adapted by the movement of the stop to engage the wind wheel 33 of the clockwork to stop the clockwork, and by the movement of the stop to its releasing position to disengage the wind wheel.

It will be seen that by this invention, the clOCkWOI'k is not suflered to run and the record strip is not paid out except when calls are made.

The clockwork stoppin action of the stop 26 may be exerted on y to engage the wind wheel 33, it being a rotatable element of the clockwork. In such case the notch 27 need not be stoppingly engaged by the pin 25 of the stop, and this the stop may be more easily disengaged from its operative position owing to absence of friction between it and such notch.

The invention being intended to be defined solely by the claims, is not to be limited to or by details of construction shown or described.
